Updating RPi to 1.0

Hello, community!
I am running Umbrel on an Raspberry Pi 4 (4 GB RAM). I followed the instructions to update to 1.0, as stated in the following.

I have not tried updating in Umbrel’s system settings. I have been keeping up with OS updates with APT via SSH.

I flashed the umbrelOS 1.0 image to a separate 8 GB SD card, but booting the Pi does nothing with it. It still works with my existing SD card, so rolling back was as easy as switching back to the previous SD card.

Any suggestions on updating to 1.0 on RPi?

Thank you!
